I am running KWSC HB, WR-IM, RDX 410 inj, 75 shot Nitrous.

Exhaust: DC Header, Cat Delete - Megan Test pipe, Skunk2 - MegaPower exhaust - silencer kinda works. It's LOUD!

Is there a axel back that will cut sound levels and provide the same or better performance? Are there other options?

Thanks

 

have a muffler shop put in a vibrant performance street muffler. lowers the decibel level and helps provide a deeper tone.

Im currently running a magnaflow 2.5" muffler with a vibrant resonator and that seems to keep the noise level down.

 

That test pipe is a big reason to why it's LOUD. I would suggest getting a high flow catalytic converter.

 

I'm looking into getting a generic twin loop style muffler (like an OBX) welded to a flange. Also the S2K stock muffler is VERY quiet.

 

What about the World Sport II muffler? It's supposed to be on the quieter side but maybe it's too restrictive for your application?
